Description

Technical Field

[0001] This utility model relates to the field of livestock breeding equipment technology, and in particular to solid-liquid separation equipment for ranches. Background Technology

[0002] During ranching, a large amount of mixed waste, including feces, urine, and flushing water, is generated. Direct discharge or storage not only occupies a lot of space but also breeds bacteria, emits odors, and causes serious pollution to the surrounding soil, water sources, and air. Solid-liquid separation is a key pre-processing step in ranch waste treatment. Through separation, waste can be divided into solid residue and liquid wastewater. The solid residue can be further processed into organic fertilizer, while the liquid wastewater can be recycled or discharged in compliance with standards after subsequent treatment, achieving the dual goals of resource recovery and environmental protection.

[0003] Traditional solid-liquid separation equipment for ranches has several shortcomings: First, its separation efficiency is low. Some equipment relies solely on gravity sedimentation or simple filtration for separation, making it difficult to quickly separate highly viscous ranch waste and prone to filter clogging, requiring frequent shutdowns for cleaning. Second, its power structure is complex. Most equipment requires multiple motors to drive the separation and conveying components separately, resulting in high energy consumption and increased equipment failure rates and maintenance costs. Third, its operation is inconvenient. The equipment is difficult to install and debug, and issues such as residue accumulation and wastewater leakage can easily occur during separation, requiring continuous monitoring by dedicated personnel. Therefore, there is an urgent need for a solid-liquid separation device for ranches that offers high separation efficiency, a simple power structure, and convenient operation to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a solid-liquid separation device for ranches.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A solid-liquid separation device for ranching includes a support frame on which an outer tube is mounted. An inner tube is rotatably connected to the end of the outer tube. Multiple sets of circumferentially spaced drainage holes are formed in the portion of the inner tube inside the outer tube. One end of the inner tube inside the outer tube is tapered and has a slag outlet fixedly connected to it. The slag outlet passes through the end of the outer tube and is rotatably connected to it. A rotating rod is rotatably connected inside the inner tube. A spiral blade is fixedly sleeved at one end of the rotating rod within the inner tube. A crossbar is fixedly connected to the end of the outer tube. A fixed plate is fixedly connected to the end of the crossbar. The rotating rod passes through the slag outlet and is rotatably connected to the fixed plate. A fixed block is fixedly connected to the upper end of the outer tube. A transmission rod is rotatably connected to both the fixed block and the fixed plate. Transmission wheels are fixedly sleeved at the ends of both the transmission rod and the rotating rod. The two transmission wheels are connected by a synchronous belt.

[0007] Preferably, a first gear is fixedly sleeved on the transmission rod, and a second gear that meshes with the first gear is fixedly sleeved at one end of the inner tube located on the outer tube.

[0008] Preferably, a motor is fixedly connected to the fixing plate, and the end of the output shaft of the motor is fixedly connected to the end of the transmission rod.

[0009] Preferably, the end of the inner tube located outside the outer tube is rotatably connected to a feed pipe in a sealed manner.

[0010] Preferably, a drain outlet is installed at the lower end of the outer pipe.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] 1. By driving the transmission rod with a motor, the inner tube rotates and the spiral blades rotate synchronously. The centrifugal force generated by the rotation of the inner tube and the pushing and squeezing action of the spiral blades work together to accelerate the separation of liquid components while performing secondary dehydration of solid residues. Compared with the traditional single separation method, the solid-liquid separation efficiency is increased by more than 40%, and the water content of solid residues is effectively reduced, laying the foundation for subsequent resource recycling.

[0013] 2. Only one motor can drive the two core components, the inner tube and the spiral blade, to operate synchronously. There is no need to equip multiple additional drive motors. This not only simplifies the power structure of the equipment and reduces energy consumption by 25%-30%, but also reduces the number of drive components and the probability of equipment failure. Subsequent maintenance only requires inspection and repair of a single motor and transmission component, which significantly reduces maintenance costs.

[0014] 3. The crossbar and fixing plate at the end of the outer tube provide stable support for the transmission components, ensuring smooth operation of the transmission structure such as the transmission wheel and gears; the tapered end design of the inner tube, in conjunction with the spiral blades, ensures smooth discharge of solid residue and enhances the squeezing and dewatering effect; the drain port at the lower end of the outer tube can quickly discharge the separated liquid components, avoiding water accumulation inside the outer tube from affecting the separation efficiency. The overall structural design takes into account both practicality and stability. Attached Figure Description

[0021] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] Reference Figure 1-5 The solid-liquid separation equipment for ranches includes a support frame 1, which is welded from carbon steel and has a high load-bearing capacity. The bottom of the support frame 1 can be fixed to the ground with expansion bolts to further enhance stability. An outer tube 2 is bolted to the support frame 1. The outer tube 2 is a seamless stainless steel pipe with a diameter of 200-300mm and a length of 1500-2000mm, designed according to the processing capacity, to ensure sufficient separation space.

[0023] One end of the outer tube 2 is rotatably connected to the inner tube 6. The inner tube 6 is also made of stainless steel, with a diameter slightly smaller than that of the outer tube 2. The two are connected by a deep groove ball bearing to ensure smooth rotation. The portion of the inner tube 6 inside the outer tube 2 has multiple sets of circumferentially spaced drainage holes 16, each set containing 4-6 holes with a diameter of 5-8 mm, effectively filtering solid residues while preventing clogging. The end of the inner tube 6 inside the outer tube 2 is tapered to facilitate the compression and dehydration of solid residues. A slag outlet 3 is welded to this end of the inner tube 6. The slag outlet 3 is a tapered stainless steel pipe that passes through the end of the outer tube 2 and is rotatably connected to it via a bearing, ensuring that the slag outlet 3 rotates synchronously with the inner tube 6 without any wastewater leakage.

[0024] A rotating rod 15, made of stainless steel with a diameter of 30-40mm, is rotatably connected inside the inner tube 6. It is connected to both ends of the inner tube 6 via bearings. A spiral blade 17 is fixedly fitted to one end of the rotating rod 15 within the inner tube 6 via a flat key. The blade height matches the inner diameter of the inner tube 6 to ensure effective material removal. A crossbar 8 is welded to the end of the outer tube 2, and a fixing plate 14, made of stainless steel, is welded to the end of the crossbar 8 to provide stable support for the transmission components. The rotating rod 15 passes through the slag outlet 3 and is rotatably connected to the fixing plate 14 via bearings, ensuring smooth operation of the rotating rod 15.

[0025] A fixing block 11, made of stainless steel, is welded and fixed to the upper end of the outer tube 2. The fixing block 11 and the fixing plate 14 are rotatably connected by a transmission rod 4 via bearings. The transmission rod 4 is a stainless steel round rod with the same diameter as the rotating rod 15. Both the ends of the transmission rod 4 and the rotating rod 15 are fitted with transmission wheels (not shown in the figure) via flat keys. Synchronous belt pulleys are used for the transmission wheels, and the two transmission wheels are connected by a synchronous belt 13 to ensure a stable transmission ratio. A first gear 9 is fitted onto the transmission rod 4 via a flat key. A second gear 10, meshing with the first gear 9, is fitted onto one end of the inner tube 6 located on the outer tube 2 via a flat key. The module and number of teeth of the first gear 9 and the second gear 10 are matched to ensure smooth transmission.

[0026] A motor 12 is bolted to the fixed plate 14. The motor 12 is a three-phase asynchronous motor, and its speed can be adjusted according to separation requirements. The output shaft of the motor 12 is fixedly connected to the end of the transmission rod 4 via a coupling, providing power to the equipment. The inner tube 6, located outside the outer tube 2, is rotatably connected to the feed pipe 5 via a sealed bearing. The feed pipe 5 is a stainless steel pipe, and the sealed bearing prevents leakage of contaminants. A drain outlet 7 is installed at the lower end of the outer tube 2 via a flange. The drain outlet 7 is a stainless steel pipe with a diameter adapted to the feed pipe, and an internal valve is installed for easy control of drainage.

[0027] Before use, this invention is fixed by bracket 1, and the feed pipe 5 is connected to the pasture waste conveying pipe, and the drain outlet 7 is connected to the sewage treatment pipe. The motor 12 is started, driving the transmission rod 4 to rotate. The transmission rod 4, via the synchronous belt 13, drives the rotating rod 15 and the spiral blade 17 to rotate, simultaneously driving the inner tube 6 to rotate via the first gear 9 and the second gear 10. The mixed waste is fed into the inner tube 6 through the feed pipe 5, and the spiral blade 17 pushes the waste towards the slag outlet 3. The rotation of the inner tube 6 generates centrifugal force, and the liquid components enter the outer tube 2 through the drain hole 16 and are discharged from the drain outlet 7. The solid residue is squeezed and discharged from the slag outlet 3. Compared to traditional solid-liquid separation devices, the dynamically configured inner tube 6 utilizes centrifugal force to accelerate liquid discharge. Simultaneously, the compression of the solid material by the spiral blade 17 and the inner tube 6 ensures thorough water separation, improving the efficiency and effectiveness of solid-liquid separation.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
